Elementary Algebra is a work text that covers the traditional topics studied in a modern elementary algebra course. It is intended for students who (1) have no exposure to elementary algebra, (2) have previously had an unpleasant experience with elementary algebra, or (3) need to review algebraic concepts and techniques.
The program which implements the Lindsey-Fox algorithm that factors high degree polynomial is organized in three stages. Jim Fox is the primary author and architect of the program.

Factoring a high degree polynomial has been considered a difficult problem since the beginning of mathematics. We describe the strategies used to attack this problem. The results are from a group called the "Polynomial Club" (Jim Fox, Sidney Burrus, Gary Sitton, and Sven Treitel)

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of moisture to the atmosphere by plants.

Students gain an understanding of the parts of a plant, plant types and how they produce their own food from sunlight through photosynthesis. They also learn about transpiration, the process by which plants release moisture to the atmosphere. With this understanding, students test the effects of photosynthesis and transpiration by growing a plant from seed. They learn how plants play an important part in maintaining a balanced environment in which the living organisms of the Earth survive. This lesson is part of a series of six lessons in which students use their evolving understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Mathematics and Statistics, Science and Technology
Students learn how scientific terms are formed using Latin and Greek roots, prefixes and suffixes, and on that basis, learn to make an educated guess about the meaning of a word. Students are introduced to the role played by metaphor in language development.
